Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535094, here are decompositions:

11 + 31535083 = 31535094
13 + 31535081 = 31535094
37 + 31535057 = 31535094
61 + 31535033 = 31535094
83 + 31535011 = 31535094
113 + 31534981 = 31535094
181 + 31534913 = 31535094
223 + 31534871 = 31535094

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.225.47.246.

Address: 1.225.47.246
Class: public
IPv4-mapped IPv6: ::ffff:1.225.47.246

Public, routable address (assignable to a host on the internet).
